Linux、Nginx、php7 redis扩展安装教程
cat > /etc/profile.d/redis.sh << EOF
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/bin’
EOF
. /etc/profile
源码安装redis
创建用户和组
groupadd redis
useradd -r -g redis -s /sbin/nologin -M redis
安装redis
cd /usr/local/src/
wget https://download.redis.io/releases/redis-3.2.5.tar.gz
tar -zxvf redis-3.2.5.tar.gz
cd redis-3.2.5/
make PREFIX=/usr/local/redis
make install
创建目录，授权
mkdir -p /usr/local/redis/data
mkdir -p /usr/local/redis/etc
mkdir -p /var/run/redis
mkdir -p /var/log/redis
chown -R redis:redis /usr/local/redis
chown -R redis:redis /var/run/redis
chown -R redis:redis /var/log/redis
配置文件
cp redis.conf /usr/local/redis/etc/
vim /usr/local/redis/etc/redis.conf
tcp-backlog 128 #tcp队列长度，CentOS系统默认为128，此值不应该大于操作系统的该值
daemonize yes #改为yes，保证redis可以后台运行
pidfile /var/run/redis/redis.pid #redis pid
logfile “/var/log/redis/redis.log” #redis日志
dir /usr/local/redis/data/ #redis数据存储目录
—— 可选配置 ——
slaveof 192.168.1.66 6379 #主从复制，在副机上配置，例：IP 192.168.1.66，端口 6379
save 60 10000 #快照，例：60s内10000个更改就保存
appendonly yes #AOF持久化
添加环境变量
cat > /etc/profile.d/redis.sh << EOF
export REDIS_HOME=/usr/local/redis
export PATH=$PATH:$REDIS_HOME/bin’
EOF
. /etc/profile
或者
vim /etc/profile
修改为下面内容，保存退出
PATH=/usr/local/mysql/bin:/usr/local/php/bin:/usr/local/redis/bin:$PATH
使/etc/profile里的配置立即生效
source /etc/profile
创建服务
vim /etc/init.d/redisd
添加如下内容
!/bin/sh
#
chkconfig: 35 84 16
Simple Redis init.d script conceived to work on Linux systems
as it does use of the /proc filesystem.
. /etc/rc.d/init.d/functions
. /etc/sysconfig/network
[ “$NETWORKING” = “no” ] && exit 0
REDISPORT=6379
BASEDIR=/usr/local/redis
EXEC=BASEDIR/bin/redis?serverCLIEXEC=BASEDIR/bin/redis-cli
PIDFILE=/var/run/redis/redis.pid
CONF=”$BASEDIR/etc/redis.conf”
function start() {
if [ -f PIDFILE]thenecho“PIDFILE exists, process is already running or crashed”
else
echo -n “Starting Redis server…”
daemon –user=redis –pidfile=PIDFILEEXEC CONF
#EXEC CONF
echo
fi
}
functionstop(){
if[!-fPIDFILE ]
then
echo “PIDFILEdoesnotexist,processisnotrunning”elsePID=(cat PIDFILE)
echo“Stopping…”
#CLIEXEC -p REDISPORTshutdownkillproc?pPIDFILE EXEC-INT
echo-n“WaitingforRedissavingdata&shutdown.”
while[-x/proc/{PID} ]
do
sleep 1
echo -n “.”
done
echo -e “\nRedis stopped”
fi
}
case “1”instart)start;;stop)stop;;status)status?pPIDFILE $EXEC
;;
restart)
stop
start
;;
*)
echo “Please use start or stop as first argument”
;;
esac
为redisd添加可执行权限
chmod +x /etc/init.d/redisd
将redis加入系统服务
chkconfig –add redisd
启动redis
service redisd start
php-redis扩展安装
wget https://101.96.10.64/pecl.php.net/get/redis-3.1.3.tgz
tar zxvf redis-3.1.3.tgz
cd redis-3.1.3
/usr/local/php/bin/phpize
./configure –with-php-config=/usr/local/php/bin/php-config
make && make install
vim /usr/local/php/etc/php.ini
添加extension = redis.so
service php-fpm restart
php -m
查看是否支持redis
测试扩展库是否正常运行
php tests/TestRedis.php –class Redis
